CAI-CLOSURE.

Specification of Letters Patent. I Patented Sept. 20, 1921.

Application iiied March 21, 1918. Serial No. 228,752.

To all'whomit'may concern:

Be it known that I, WALTER C. FOELL, a citizen of the United States,residing at Waterbury, in the county of New .Haven and State ofConnecticut, have invented certain new and useful Improvements in aCap-, Closure, of which the following is a specification.

This invention relates to improvements in closures for bottles and jarsand it is the principal object ofv the Invention to provide a novel formof cap closure adapted to be applied over the mouths of bottles andother receptacles and secured by crimping or like modes of distortion tothe necks of the same and which, when desired, can be quickly removedtherefrom but when engaged with the bottle will serve as a'highlyefiicient and positive seal therefor.

' Other objects will be in part obvious and in art pointed outhereinafter.

he improvements in the details and ar-' rangement of parts will beapparent from an inspection of the accompanying drawings, in connectionwith the specific description hereinafter contained, and whereinthepreferred embodiment of the invention is disclosed for the purpose ofimparting a full understanding of the same.

In the drawings:

Figure 1 is a side elevation of the improved cap closure as applied to aportion of a bottle neck,

Fig. 2 is a vertical section therethrough,

Fig. 3 is a vertical section through the cap showing the relativearrangement of the same and the; closure disk before the lower portionthereof is crimped, and

Fig. 4 is a fragmentary horizontal section through a portion of the capand thebottle neck showing the same crimped.

Having more particular reference to the drawings, in connection withwhich like reference characters will designate-corresponding partsthroughout the several views-of the .drawings, 1 representsthe neck ofthe bottle, 2 the usual curved shoulder formed thereon directly'belowthe mouth of the same and 3 the curved beading formed upon the upper endof the same adjhcent its mouth; this construction being common inconnection withthe-manufacture of bottles for containing different formsof beverages and the like.

The improved closure comprises a cap designated in its entirety by thenumeral 4,

the intermediate portion of the annular sides thereof being crimped toform an annular inwardly extending rib 5, while the lower portion of thecap sides are adapted to be connected or engaged over the curved beading3 by crimping as indicated at 6 or I by other suitable forms ofdistortion.

A sealing disk 7 is provided and is adapted to be arran d over the mouthof the bottle neck 1; t e marginal portion of said disk extending for adistance onto the curved heading 3 in order that the slanting face ofthe rib 5 formed in the annular sides mouth when the lower portion ofsaid cap is crimped or otherwise distorted as at 6 in order to insureengagement between the same and said curved beading 3. With the cap thusapplied over the bottle neck mouth, it will be readily understood thatthe bottle will be efliciently and positively sealed, thus, permittingthe contents of the same to be effectually preserved.

Attention is directed to the fact, that the upper portion of the closurecap 4 is extended for a distance above the bottle neck, as clearly shownin the Figs. 1 and 2. Hence, when it'is desired to disengage the closurecap from the bottle neck, it is only necessar to sharply or abruptly tapthe top of the .c osure cap, thereby forcing the same downwardly andcausin an outward riding engagement of the slanting face of the rib 5with the disk and the beaded portion 3 and to ride over the curvedshoulder 3 and as a' consequence, the crimped portion 6 thereof will bespread sufliciently to allow the closure cap to be freely withdrawn fromengagement with the bottle neck. The circular side wall of the cap 4lying between the rib 5 and closed end is of uniform diameter throughoutthus providing a rightangular corner which is disposed so prominentlythat it ma be conveniently struck against a wall or ot er object 'to'remove the cap from the bottle.

From the fore oing, it will be understood by persons skille in the artthat I have provided an exceedinglly cheap, sim 1e and eflicient form ofbott e closure an one which by reason of its construction may be quicklyand readily disengaged from a bottle neck, thus, saving considerabletime and quite often, reventing the wasting of the contents oi thebottle or the fracturing of the bottle neck in attempts to remove theclosure a ward movement of the same over said neck.

Further, the cap may be formed of any suitable material, such as sheetmetal or the like, "such as conditions or preference may dictate.As'indicated, I do notwish to be understood as confinlng' the inventionto the par- ,ticular' embodiment chosenfor illustration -herein, 'nor tothe exact construction, ar-

' rangement and adaption of parts shown am:I described, but I reservethe right to ma fall within the spirit and scope of the invention. I

I claim:

The combination with a bottle having an outwardly directed annular beadat its mouth and an annular enlargement next the bead, of a capcomprising a cylindrical body closed at the outer end and with aninwardly directed rib intermediate the ends, the portion of said capbetween the rib and its open end adapted to be crimped into the spacebetween the bead and the enlargement to lock the cap in position, thecap being detachable by pressure applied to the ca longitudinally of thebottle to-force the ri over the bead and the crimped portion over theenlargement.

V In testimony whereof, I aflix my signature hereto.
